toward High Energy Physics
T. Tajima
IZEST
1. Fundamental physics with intense lasers
2. Laser acceleration to high energies (100GeV, TeV and beyond):
need for large-energy laser (PETAL @ LMJ)
3. Collider and Low Luminosity Paradigm
4. High-average power lasers (ICAN Project)
5. Low-energy new fields: Frontier of large number of coherent photons:
Dark Matter and Dark Energy fields
‘Shake the vacuum’ by degenerate 4 (laser) wave mixing
6. Mission of IZEST:
kJ [large photon number (=Avogadro number)] laser (PETAL)
+ high-average power laser (ICAN)
toward fundamental physics
in the international networking
(with many willing labs to cover broad parameters)

21st Century; the Photon Century
Could basic research be driven
by the massless and chargeless particles;
Photons (photonics)?

IZEST’s Missions
• An international endeavor to unify the high Intensity laser
and the high energy / fundamental physics communities to
draw
“The Roadmap of Ultra High Intensity Laser”
and apply it to
“Laser-Based Fundamental Physics”
・
To form an international team of scientists that can foster
and facilitate scientific missions of EW/ZW class lasers and
high average power lasers (ICAN) comprised from ICFA and
ICUIL communities (in collab)

•High sensitivity of the coherent large photon number:
Luminosity (per shot) N3/ τ [N the number of laser photons
(~Avogadro number), τ the pulse length]: N3/ τ ~ 1070 (N3f/ τ
when rep-rate f is applied, could be greater than 1080 per year)
